An integrated Fiber-To-The-Homes (FTTHs) and Wireless Sensor Network (WSN) provides a cost-effective solution to build up an immaculate Ubiquitous-city (U-city). The key objectives of effective convergence of FTTH and WSN are less computational complexity for data packet processing, low installation cost, and good quality of services. In this paper, the authors introduce an integrated network structure of multi-Optical Line Terminal (multi-OLT) Passive Optical Network (PON) which can accommodate multiple service providers in a single PON. A modified version of interleaved polling algorithm is proposed for scheduling of control messages from multiple OLTs in a single network.
